As shown in fig. 1-5, a thermostat comprises a housing, a valve core; the shell comprises a water inlet shell 1 and a water outlet shell 2, wherein the water inlet shell 1 is used for being connected with a water outlet pipeline of the cylinder cover, and the water outlet shell 2 is used for being connected with a water inlet pipeline of the radiator; the end of the water inlet shell 1 forms a first water inlet 11, and the joint of the water outlet shell 2 and the water inlet shell 1 forms a second water inlet 21. The valve core is arranged in the shell and penetrates through the upper surface of the water inlet shell 1. The water inlet shell 1 and the water outlet shell 2 are both in a straight-through cylindrical arrangement, specifically, the axes of the valve core, the water inlet shell 1 and the water outlet shell 2 are arranged in the same straight line, cooling liquid can flow through the thermostat in a straight line and then reach the radiator, the flow of the cooling liquid is smooth, heat cannot be accumulated, the heat dissipation effect can be effectively improved, and energy consumption is reduced.

Specifically, the valve core includes a push rod 31, a first opening/closing valve 32, a second opening/closing valve 33, a spring 34, and a push rod controller 35. The spring 34 is sleeved on the upper portion of the push rod 31 and located above the first opening and closing valve 32, the push rod controller 35 is connected to the lower portion of the control push rod 31, and the push rod controller 35 is used for moving the push rod 31 up and down.
